DUMP-CAR.

Specification of Letters Patent.

Fatented Nov. t9, ltlul Application filed November 14, 1910, Serial No. 592,222.

T0 all whoa/'1,- f/t' may concern:

it known that l, @rre lll/*nimmt Meissnnn, a citizen of the United States of America, and a resident of lvlontreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful lmprovements in Dump-Cars; and l do hereby declare that the following is a full, clear, and exact description of the same.

lvly invention relates to cars and particularly to convertible cars which are adapted to be used either as dump cars or general service freight.

My invention has for its object 'to provide an improved construction for certain of the parts of the car as will be pointed out in the following description, the invention consisting essentially of the particular construction, arrangement, and combination of parts as hereinafter set forth. ll'or full comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate the saine parts and whereinlligure l is a side elevation partly in section of a car having my invent-ion embodied therein; Fig. is a horizontal sectional view thereof taken on line fi il Fig. 3; Fig. 3 is a transverse sectional view taken on line B l l'lig. l; llig. 4t is an underside plan view of a portion of the car; and Fig. 5 is an enlarged detail ectional view taken on the line ll B l? ig. l.

rllhe understructure of the car on which the car body is supported comprises a center sill. o in the form of al hoi; girder and having laterally extending arms l) riveted or otherwise rigidly secured thereto and between which the trap doors for discharging grain or other loose material, and which will be presently further described are located, the outer ends of the arms supporting Z- shaped side stifteners o secured thereto. The frames (Z for the trap doors are preferably formed of angle bars with downwardly projecting flanges e and are suitably secured by rivets or otherwise at their ends and sides respectively to the arms o and the center sill a. and side stilfeners c, these frames being secured directly to the arms b and side stifl'- cners c and to the center sill hy means of transverse members f rigidly mounted on the lat-ter and to which the frames d are fastened, these frames serving to stillen the undcrstructure to better resist strains or corner shocks.

rEhe doors g present flanges g at their ends and inner sides, the outer sides being open, thus constituting a trough particularly adapted for rapid unloading. These doors are arranged in two series disposed on opposite sides of and hinged by hinges 7L to the center sill a. and extending from end to end of the car, and arranged to swing downwardly and inwardly to cause the material to be discharged toward the sides of the car while the hinges or pivot points of the doors of each series are in line with one another so that all the doors swing on a common axis and may therefore be readily operated in unison.

vlhe free ends of the doors which constitute the open ends of the trough are sealed or closed by angular valvular nien'ibcrs 21 provided with means whereby they may be swung underneath the doors when the latter are opened, such means being preferably arranged to act automatically. ris shown in the drawings the member o' secured near its opposite cnds to the ends of a pair of door-rail arms j pivoted attvheir other ends as at 7c to a pair of tired door-rails Z secured by rivets or other suitable means on the underside of the door at opposite ends thereof. These arms j are caused to turn on their pivots to swing the members c' under the door, by means of a pair of links m located adjacent to the opposite ends of the door and which are cach connected at one end by a sliding pivotal connection to the lateral arms such sliding pivotal connections being effected by studs a projecting` from brackets n secured to the arms b, theseI studs n passing through slots o in the links. The opposite ends of these links are pivotally connected 'to studs 2a projecting from plates y) riveted to the member 'e'.

Mounted on opposite sides of each door are a pair of teats s which are adapted as will be pointed out later, to bear upon the links and cause the valvular members to be swung away from the free ends of the doors and under the latter as they open in the event of the valvular members failing to Vmove thus through the action of gravity.

The door operating means comprises laterally movable horizontal shafts l, l and 2, 2, extending longitudinally of the car on opposits sides of the center sill beneath the diagonal doors and on which the outer sides of the latter are supported, the shafts 1 and 2 eX- tending from one end of the car to the center thereof and the shafts l and 2, extending from the opposite end of the car to the center, these shafts being supported at their vinner ends by the center arm as shown in Fig. l. rhese shafts in turn rest on and are adapted to roll or travel on transverse rails 3 inclined upwardly toward their outer ends and preferably formed by the lower walls of inclined slots l in the lateral arms b. To these shafts are attached the ends of chains 5 which are fastened at their opposite ends to angular extensions of the arms Upon rotation of the shafts the chains are caused to wind thereupon or unwind therefrom whereby the shafts will be caused to travel up or down the inclined rails to close or open the doors, each of these shafts being operated by levers 6, loosely mounted on the opposite e ds thereof which project slightly beyond the ends of the car; operative connection between the levers and shafts being effected by any suitable means, the means here indicated comprising pawls 7 pivoted on the levers and engaging with ratchet. wheels 8 rigid on the ends of the shafts, while the shafts are locked by means of pawls 9 engaging ratchet wheels 10 on the shafts. The pawls 9 are pivoted on a floating plate 11 which travels with the shaft, the end of the latter project-ing therethrough.

When the doors are being operated the shafts l and 2 travel under the fixed doorrails Z and the door-rail arms j, the rails Z inclining upwardly toward the inner edges of the doors.

In order that the shafts may be caused to force the doors tightly against the door frames when the doors are closed the door rail ari s y' are tapered to cause their rail surface j to be inclined upwardly toward the outer ends of the doors to present a diminished angle of convergence to the rails 3 so that the shafts may be wedged therebetween and the arms j when the doors are closed. By mounting the valvular members on the door-rail arms j the wedging of the shafts therebetween and the rails 3 not only closes the doors tightly but also acts to hold the valvular members firmly in position closing the open or free ends of the doors.

As will be seen from the foregoing description this invention provides a car the doors of which are, when closed, proof against leakage, and, in addition the operating thereof is facilitated.

in order that the car may be converted when desired into a general service freight car when it is not desired to use it for the conveyance of grain or like material it is provided with a flooring located just above the door frame CZ, the portion of the flooring over the doors g being removable, the dooring being divided longitudinally into three sections comprising end and middle sections, such sections being disposed in pairs and hinged as at 16 to opposite sides of the car. The end sections 17, 17, and 18, 1S, are of a width substantially equal to the width of the door openings, the balance of the floorin g between such sections being formed by center floor sections 19 and 2O permanently secured in place. The middle sections, 2l, are each of a width substantially one half that of the car so that when in position their free edges abut, these sections acting as bridging members between the usual side doors 22 of tne car, contiguous to which they are placed, and the center' sections 19 and 20.

VJhen the car is to be used as a grain car the sections 17, 17, and 1S, 1S, are swung up to a vertical position alongside the walls of the car, as shown in Figs. 1, 2 and 3, the middle sections thus forming grain doors,

shown clearly in liig. 1.

The side walls 30, in which the doors 22 are located, end walls 3l. and roof 32 of the car body are supported by a steel frame superstructure comprising uprights 33 supported by the arms t) and connected together at their tops by longitudinal members 34, transverse rafters carried by these members supporting the longitudinal roof beams 3G.

Gperation: lVhen the car is to be used as a dump car for the conveyance of grain or the like the side floor members are swung to a vertical position alongside the side walls 30, leaving the trap doors g exposed and the car is filled in the usual manner through the opening 37 in the end wall 31. lllhen it is desired to unload the car the doors g are opened by operating levers 6, the shafts l, 1 and 2, 2 unwinding from the chains 5 and rolling down the inclined rails 3, and the weight of the doors and material piled 'thereon causing them to swing open. The opening of the doors causes the valifular members i to be swung thereunder as follows As the shaftsin their travel down the rails 3 move from under the door rail arms j the latter are released and the valvular members z' will fall by gravity until the links m rest on the shafts, and as the' shafts continue their movement and the doors open he valvular members will continue to swing downwardly until the position shown in Fig. 5 is reached, the further movement of the doors causing t through the action of the links m) the arms and valvular members to swing in the direct-ion indicated by the arrow to the position shown at the left side of Fig. 3 in which position the doors are fully open, the valvular members being thus protected from rain, sleet or the like, the slots in the links accommodating the difference in the distance between the ends of the arms and the studs n when the doors are in open and closed position. ln case the valvular members when released should tail to swing' away from the end o'l' the doors or it atte1 reaching the position shown in Fig. o they should tend to swing in the wrong direction, the teats s on the sides ot' the doors will bear upon the links and cause them to swing the arms and valvular members in the proper direction.

To close the doors the shafts l and 2 are caused to roll up the rails 3 by operating the levers 6 and winding the chains thereon, the shafts in their travel bearing successively against the undersides ot' the doors, the fixed rails Z and the arms j between which latter and the rails 3 they are finally wedged, thus holding the doors firmly closed with the valvular members closing the free ends thereof.

When using the car as a dump car tor the conveyance ot material which is not possible to load therein through the opening 37 the middle tloor sections 2l may be swung down to form a bridge between the door i8 and the central A.Floor sections 19 and 20, a runway being thus formed by the bridging members and the center sections 'for trucks or the like carrying the material with which the car is being loaded.

lWhen the car is to be used as a general service freightcar all the members forming the side sections are swung down and the car is thus ijirovided with an even flooring for the piling of material thereon.

llllhat l claim is as follows 1* 1. ln a dump car, the combination of a trap door, a valvular member secured to the door and adapted to seal one end thereof, and means actuated by the movement of the door adapted to automatically swing the valvular' member away from the said end.

2. in a dump car, the combination ot a center sill, a plurality o1PA arms spaced apart and extending laterally from the center sill on opposite sides thereof, a plurality oit trough shaped doors located between said arms and arranged in two series on opposite sides oit and being hinged to the center sills, said trough shaped doors being open at their outer ends, valvular' members closing the open ends ol such trough shaped doors, and means tor swinging said valvular members away from the open ends olf the doors and underneath the latter.

3. ln a dump car, the combination of a center sill, a plurality of arms spaced apart and extending laterally from the center sill on opposite sides thereol, a plurality of trough shaped. doors located between said arms and arranged in two series on opposite sides ot and being hinged to the center sill, said trough shaped doors being open at their outer ends, valvular members closing the open ends ot such trough shaped doors, and automatically acting means l'or swinging said valvular members away 'from the open ends ot and underneath the doors when the latter are opened.

d. in a dump car, the combination ot' a conte sill, a plurality ot arms spaced apart and extending laterally from the center sill on opposite sides thereof, a plurality et trough shaped doors located between said arms and arranged in two series on opposite sides et and being hinged to the center sill, said trough shaped doors being open at their outer ends, valvular members closing the open ends of such trough shaped doors, means for sin'iultaneously opening and closing all the doors in either series, and automatically acting means 'tor swinging said vaivul ar members away from the open ends of and underneath the doors when the latter are opened.

5. A dump car having a center sill, a plurality of arms spaced apart and extending laterally from such center sill, side sills connecting the ends of the said lateral arms, a plurality ot upwardly flanged doors located between such late al arms and frames for such doors, such trames comprising angle bars having downwardly projecting tlanges adapted to be inclosed by the said upwardly projecting door flanges, theY said frames being secured to the said lateral arms and center and side sills and serving to stillen the car trame against diagonal strains.

ln testimony whereof, l have signed my name to this specification, in the presence of two subscribing witnesses.
